What is a committer?

Technically, a committer is someone who has write access to the Chromium Git repository or the Chromium OS Git repository. A committer can submit their own patches or patches from others.

This privilege is granted with some expectation of responsibility: committers are people who care about the Chromium projects and want to help them meet their goals. A committer is not just someone who can make changes, but someone who has demonstrated their ability to collaborate with the team, get the most knowledgeable people to review code, contribute high-quality code, and follow through to fix issues (in code or tests).

A committer is a contributor to the Chromium projects' success and a citizen helping the projects succeed. See Committer's responsibility.

Becoming a committer

In a nutshell, contribute 10-20 non-trivial patches and get at least three different people to review them (you'll need three people to support you). Then ask someone to nominate you. You're basically demonstrating your

commitment to the project (10+ good patches requires a lot of your valuable time),

ability to collaborate with the team,

understanding of how the team works (policies, processes for testing and code review, OWNERS files, etc),

understanding of the projects' code base and coding style, and

ability to write good code (last but certainly not least)

A current committer nominates you by sending email to committers@chromium.org containing the following information. Please do not CC the nominee on the nomination email.

your first and last name

your email address. You can also ask to get an @chromium.org email address at this time, if you don't already have one.

Two other committers need to second your nomination. If no one objects in 5 working days (U.S.), you're a committer. If anyone objects or wants more information, the committers discuss and usually come to a consensus (within the 5 working days). If issues can't be resolved, there's a vote among current committers.

That's it! There is no further action you need to take on your part. The committers will get back to you once they make a decision.

In the worst case, this can drag out for two weeks. Keep writing patches! Even in the rare cases where a nomination fails, the objection is usually something easy to address like "more patches" or "not enough people are familiar with this person's work."

Once you get approval from the existing committers, we'll send you instructions for write access to Git. You'll also be added to committers@chromium.org. If you work for Google, you are expected to become a sheriff at this point as well (see the internal instructions for how to add yourself to the rotations).

Other statuses

Try job access

If you are contributing patches but not (yet) a committer, you may wish to have be able to run jobs on the try servers directly rather than asking a committer or reviewer to do so for you. To get access:

If you have an @chromium.org email address and wish to use it for your account:

Fill in the request form at Chromium access (read-only, so leave the Write access box unchecked, and write "Try access" in the comments).

If you do not have an @chromium.org email address, or wish to use a different email address;

Ask someone you're working with (a frequent reviewer, for example) to send email to accounts@chromium.org nominating you for try job access.

You must provide an email address and at least a brief explanation of why you'd like access.

It is helpful to provide a name and company affiliation (if any) as well.

It is very helpful to have already had some patches landed, but is not absolutely necessary.

If no one objects within two (U.S.) working days, you will be approved for access. It may take an additional few days for the grant to propagate to all of the systems (e.g., Rietveld) and for you to be notified that you're all set.

Maintaining committer status

You don't really need to do much to maintain committer status: just keep being awesome and helping the Chromium projects!

A community of committers working together to move the Chromium projects forward is essential to creating successful projects that are rewarding to work on. If there are problems or disagreements within the community, they can usually be solved through open discussion and debate.

In the unhappy event that a committer continues to disregard good citizenship (or actively disrupts the project), we may need to revoke that person's status. The process is the same as for nominating a new committer: someone suggests the revocation with a good reason, two people second the motion, and a vote may be called if consensus cannot be reached. I hope that's simple enough, and that we never have to test it in practice.
